Hi all, I'm trying to configure nagios 3.0.6 so that I can add contact groups to a host by adding a host template to the host definition. I have one host template called 'unix-host' that I'm using to aggregate the Unix Team contacts into a template. I have another host template called 'oncall-host' that I'm using to represent people on call 24x7. If a host is critical enough that the on-call people should be alerted if it goes down, I want to be able to add the 'oncall-host' host template as a template for the critical host, have the 'unix-host' host template as another template for the host, and have nagios alert both the people on call and the Unix Team admins if the host goes down. The on-call people should be alerted by SMS and email every 5 minutes, but the Unix Team admins are should only be alerted by email every 10 minutes. I have an email server called 'doris' that is currently down, and is configured as specified below. What's happening is that the on-call people are being alerted by SMS and email every 10 minutes (which is as it should be), but the Unix Team admins aren't being alerted at all. If I remove the 'oncall-host' template from the host definition, the Unix Team admins are alerted by email as they should be. Can anyone suggest how I might get the alerting working, and still be able to just add the 'oncall-host' template as a template for a critical host? Perhaps it would be better to do this with hostgroups? Here are all my definitions... sorry if it's a bit convoluted: Here's the host definition for the host in question: define host { host_name doris alias doris email server address 192.168.2.25 parents sw-l3-mail use oncall-host,unix-host register 1 } 'unix-host' host template: define host { name unix-host alias Unix Team host template use generic-host contact_groups +unix-admin register 0 } 'oncall-host' host template: define host { name oncall-host alias Host template for critical hosts use generic-host contact_groups oncall-primary notification_interval 5 register 0 } 'generic-host' host template: define host { name generic-host alias Top-level host template check_command check-host-alive max_check_attempts 10 check_interval 5 retry_interval 1 active_checks_enabled 1 check_period 24x7 obsess_over_host 1 check_freshness 1 event_handler notify-host-by-email event_handler_enabled 1 flap_detection_enabled 1 process_perf_data 1 retain_status_information 1 retain_nonstatus_information 1 notification_interval 10 notification_period 24x7 notification_options d,u,r notifications_enabled 1 failure_prediction_enabled 1 register 0 } 'unix-admin' contact group: define contactgroup { contactgroup_name unix-admin alias Unix Team Admins members nagiosadmin } 'oncall-primary' contact group: define contactgroup { contactgroup_name oncall-primary alias On-call Primary members oncall_phone1 } 'nagiosadmin' contact: define contact { contact_name nagiosadmin alias Nagios Admin contactgroups unix-admin email <a href="mailto:nagiosadmin@mydomain.co.uk">nagiosadmin@mydomain.co.uk</a> use human-contact } 'oncall-phone1' contact: define contact { contact_name oncall_phone1 alias On-call Phone #1 contactgroups oncall-primary email <a href="mailto:phone1@mydomain.co.uk">phone1@mydomain.co.uk</a> pager 07555555555 use oncall-contact } 'human-contact' contact template: define contact { name human-contact alias Human contact template contactgroups unix-admin host_notification_period 24x7 service_notification_period 24x7 host_notification_options d,u,r service_notification_options w,u,c,r host_notification_commands notify-host-by-email service_notification_commands notify-service-by-email use generic-contact register 0 } 'oncall-contact' contact template: define contact { name oncall-contact alias On-call contact template contactgroups oncall-primary host_notification_period 24x7 service_notification_period 24x7 host_notification_options d,r service_notification_options u,c,r host_notification_commands notify-host-by-email,notify-host-by-sms service_notification_commands notify-service-by-email,notify-service-by-sms use generic-contact register 0 } 'generic-contact' contact template: define contact { name generic-contact alias Highest-level contact template host_notifications_enabled 1 service_notifications_enabled 1 host_notification_period 24x7 service_notification_period 24x7 register 0 } Regards, Guy.
